Description

[Technical Field]

[0001] The present invention relates to a rhythm signal output device that can output a signal at a constant rhythm. [Background technology]

[0002] Conventionally, there are various percussion instruments such as drums, tambourines, and castanets as instruments for keeping rhythm. However, in order to keep a consistent rhythm using these percussion instruments, considerable training and skill is required, and there is a problem that those with less skill will inevitably lose their rhythm. To solve this problem, electronic rhythmic musical instruments have been proposed, such as rhythm machines, rhythm boxes, and drum machines, which automatically output rhythmic sounds from speakers based on preset rhythms and output sounds. Summary of the Invention [Problem to be solved by the invention]

[0003] With the rhythm electronic musical instrument described above, even an untrained person with low skill level can keep a consistent rhythm. However, with electronic rhythm instruments, the rhythm is not created by a person but by an electronic instrument, so the enjoyment of playing music is lost.Also, it cannot be used in situations where you want to improvise rhythms, such as clapping along to a set rhythm in a karaoke booth or at a concert. In view of the above-mentioned problems of the conventional art, the inventors have an object to provide a rhythm signal output device that allows even untrained people to easily keep a consistent rhythm anywhere. [Means for solving the problem]

[0004] In order to achieve the above-mentioned object, the rhythm signal output device of the present invention comprises a support, an elastic body having one end fixed to the support and the other end extending beyond the support and capable of vibrating in a direction toward and away from the support, a weight attached to the other end of the elastic body, a switch attached to the elastic body and / or the support and turned on and off by the elastic body in response to the vibration of the elastic body, and an output circuit connected to the switch, wherein the switch is turned on and off by the vibration of the elastic body, thereby outputting a rhythm signal in accordance with the natural frequency adjusted by the elastic body and the weight. The switch may be configured to have two terminals connected to an output circuit, one terminal fixed to an elastic body, the other terminal consisting of two contacts, one contact fixed to a support, and the other contact fixed to the elastic body, and the two contacts coming into contact and separating in response to vibration of the elastic body, and when the two contacts come into contact, the elastic body forms part of the output circuit and turns the switch ON. The switch may also be configured to have two terminals connected to an output circuit, one terminal fixed to a support and the other terminal consisting of two contacts, one contact fixed to the support and the other contact fixed to an elastic body, and the two contacts come into contact and separate in response to vibration of the elastic body, and when the two contacts come into contact, the support may form part of the output circuit and turn the switch ON. Furthermore, the switch may be a microswitch equipped with a snap action mechanism, and the microswitch may be provided on a support or an elastic body so as to be turned on / off by vibration of the elastic body. Preferably, the output circuit can be connected by wire or wirelessly to an output device having a program that outputs sound, image, light and / or movement based on the rhythm signal. [Effects of the Invention]

[0005] The rhythm signal output device of the present invention comprises a support, an elastic body having one end fixed to the support and the other end extending beyond the support, and capable of vibrating in a direction toward and away from the support, a weight attached to the other end of the elastic body, a switch attached to the elastic body and / or the support and turned on and off by the elastic body in response to the vibrations of the elastic body, and an output circuit connected to the switch, and is configured so that the switch is turned on and off by the vibrations of the elastic body, thereby outputting a rhythm signal corresponding to the natural frequency adjusted by the elastic body and the weight.Therefore, when a user simply holds the support in their hand and shakes it, the elastic body vibrates at a predetermined frequency, turning the switch on and off at a constant rhythm, and enabling a rhythm signal of a constant rhythm to be output from the output circuit. This allows the output circuit to be connected, via a wired or wireless connection, to any output device equipped with a program that outputs sound, images, light, and / or motion based on a rhythm signal. For example, if the program is a program that outputs the sound of a musical instrument such as a drum, even non-experts can output drum sounds, etc. at a constant rhythm, allowing them to enjoy playing music. If the program is a program that moves an image in response to a rhythm signal, it can be used to practice keeping rhythm while moving the image, or it can be used as a toy. If the program is a game program that uses a rhythm signal as an input signal, even users who have not practiced keeping a constant rhythm can enjoy the game. Furthermore, if the program is a program that flashes lights in response to a rhythm signal, it can be used to flash the lights of a smartphone, etc. at a constant rhythm in place of cheering at concert venues, etc., where it is not permitted to shout out in recent years. Furthermore, if the program is a program that can move the arms, legs or head of the doll in response to a rhythm signal, the user can make the doll dance by operating it.

[0007] BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of a rhythm signal output device according to the present invention will be described with reference to several examples shown in the accompanying drawings. FIG. 1 is a schematic diagram of an embodiment of a rhythm signal output device according to the present invention. In the drawing, the entire rhythm signal output device is designated by reference numeral 1. The rhythm signal output device 1 shown in FIG. The elastic body 3 has a vibrating leaf spring shape, one end of which is fixed to the support body 2, and the other end of which extends beyond the support body 2 to the outside (upward in the illustrated embodiment). A weight 4 is attached to the other end of the elastic body 3, and the natural frequency of the elastic body 3 is adjusted to a predetermined natural frequency by the weight 4. The frequency of the elastic body 3 is adjusted by the length of the elastic body 3, the elastic force of the elastic body, and the weight of the weight 4, and is preferably adjusted to 120 to 160 BPM (beats per minute). The support body 2 and elastic body 3 configured as described above are provided with a switch consisting of a first terminal 5 and a second terminal 6, and the second terminal 6 consists of a first contact 6a and a second contact 6b. The first contact 6a of the first terminal 5 and the second terminal 6 is fixed to the support body 2, and the second contact 6b is fixed to the elastic body 3 at a position corresponding to the first contact 6a of the second terminal 6. The first terminal 5 and the second contact 6b of the second terminal 6 are connected to an output circuit 7, and at least the portion of the support 2 between the first terminal 5 and the first contact 6a of the second terminal 6 is formed of a conductor. According to the above-described configuration, as shown in Figures 2 and 3, when the elastic body 3 vibrates and moves in a direction toward the support body 2, the first contact 6a and the second contact 6b come into contact and the switch is turned ON, the support body 2 forms part of the output circuit 7 and the output circuit 7 is turned ON (see Figure 2), and when the elastic body 3 moves in a direction away from the support body 2, the first contact 6a and the second contact 6b separate, the switch is turned OFF, and the output circuit 7 is also turned OFF. As described above, the natural frequency of the elastic body 3 is adjusted to a predetermined frequency by the weight 4, so that when a user holds the support body 2 in his / her hand and shakes the rhythm signal output device 1, the elastic body 3 vibrates at the predetermined frequency, causing the output circuit 7 to repeatedly turn ON / OFF via the switch at a constant rhythm. The output circuit 7 is connected to an arbitrary output device 8 by wire or wirelessly (wirelessly, for example, Wifi or Bluetooth, in the embodiment of FIGS. 1 to 3), and outputs a constant rhythm signal to the output device 8. The support 2 and the output circuit 7, and if necessary, a part of the elastic body 3, may be preferably housed in a housing 9.

[0008] The output device 8 outputs in the form of sound, image, light or movement in response to the rhythm signal. Specifically, for example, if the output device 8 is configured as a smartphone, the smartphone may be provided with a program that outputs drum sounds and the like in response to a rhythm signal. With this configuration, even non-experts can output drum sounds and the like at a consistent rhythm, allowing them to enjoy playing music. Furthermore, if the output device 8 is configured as a smartphone, the smartphone can be equipped with a program that moves images in response to rhythm signals. This configuration allows users to practice keeping rhythm while moving the images, and can also be used as a toy. Furthermore, if the output device 8 is configured as a smartphone, a game program that uses a rhythm signal as an input signal can be installed on the smartphone. Furthermore, if the output device 8 is a smartphone, the smartphone can be programmed to flash its lights in response to a rhythmic signal. This configuration makes it possible to use the smartphone to flash its lights in a set rhythm in place of cheering, for example, at concert venues where people are not allowed to shout out loud these days. The output device 8 is not limited to a smartphone, but may be any device capable of executing a program operable based on an input signal, such as a personal computer, a tablet, or a specially designed device. A specific example of a specially designed device may be a doll whose arms, legs, or head move and start dancing in response to a rhythmic signal.
